HSPG founders launch two new businesses as affordable housing investor demerges

Social impact investor HSPG has demerged.

The affordable housing funder’s co-founders Guy Horne and David Searle have announced they are de-merging to form two businesses called Sevet and Highdale which they will wholly-own individually .

Sevet, owned by Guy Horne will focus on affordable housing delivery. Its primary focus will be on Archie Homes, a for-profit provider previously known as Park Properties Housing Association, which is a joint venture with San Francisco-based global investor Sixth Street Capital Partners.

Archie Homes has a contracted pipeline of around 1,000 homes and earlier this year secured £1bn of equity funding from Sixth Street.

Archie Homes in August became one of only three for-profit registered providers appointed as a Homes England Strategic Partner. It secured a £148.9m funding allocation to support the delivery of 1,500 affordable homes.

Searle’s Highdale will focus on real estate investment and asset management.

HSPG’s staff members have moved across to one of the two businesses.

Horne and Searle - two graduates and former “child entrepreneurs” - founded HSPG in 2025, buying and refurbishing low-cost homes in Manchester to house homeless families referred by charities, before selling the properties on.

Guy Horne, chief executive of Sevet, said: “This next chapter gives us the opportunity to bring even greater focus to our mission and accelerate the delivery of affordable housing across the UK.

”Through Archie Homes and our continued partnership with Sixth Street, we have the capital, experience, and strong pipeline of opportunities in place to help thousands more people access safe, secure and affordable homes in the parts of the country where they are needed most.”

David Searle, founder of Highdale, said: “Our complementary strengths have always been central to HSPG’s success, and creating two independent businesses gives us the freedom to apply those strengths with greater focus.”
